Clean up the waterproofing membrane carefully (well-swept)

3.2

.2 Careful inspection of the waterproofing membrane including seams, penetrations and details after flood testing or electronic leak detection. If the waterproofing system and the Green Roof system are not carried out by the same company, the acceptance of the method used for waterproofing quality should be agreed by all the parties (see section 1.5.3.). Identified defects are to be reported in written form. Do not proceed until corrected.

Moisture retention and protection mat

.1 Deliver and install the ZinCo protection mat SSM45 directly on the top of the root barrier with a minimum overlap of 100 mm, according to the manufacturers instructions. The protection mat has to be taken above the growing medium along the edges and roof penetrations. Cut the protection mat in place at the roof penetrations.

OR (PLEASE CHOOSE CONVENTIONAL OR INVERTED)

Diffusion membrane

.2 In the case of an inverted roof: Deliver and install the ZinCo diffusion membrane TGV21 directly on the top of the insulation with a minimum overlap of 100 mm, according to the manufacturer’s instructions. The separation sheet must be installed above the growing medium along the edges and at roof penetrations.

3.3

Drainage element

.1 Deliver and install the ZinCo drainage and water storage element Floradrain ® FD25-E or FD40-

E directly on the protection mat or diffusion membrane according to the manufacturers instructions.

Install the Floradrain elements side by side with the ventilation and evaporation holes facing down and fix the elements together with connection clips or overlap them. Cut the drain elements in place along the edges and roof penetrations. Fill the water retention cups of the drain layer once with water.

3.4

Bedding material

.1 Deliver and install the High Performance Bedding material on the drainage layer. Spread out the bedding material equally to the required depth with a minimum of 50 mm. Check the depth on several places to ensure the right thickness. A tolerance of 1 cm is acceptable. Compact the bedding material with a roller.
